AIM　The purpose is to investigate the Anti-inflammatory mechanism of Biota orientalis. METHODS　Using rat leukocytes and rabbit platelets as experimental material the biosynthesis of leukotriene, 12-hydroxyheptadecatrienoic acid(12-HHT) and 12-hydroxyeicosatetraenoic acid(12-HETE) in the cells was determined with HPLC. RESULTS　Biota orientalis was shown to inhibit the biosynthesis of leukotriene B4(LTB4) and 5-hydroxyeicosatetraenoic acid(5-HETE) with IC50 of 0.40 and 0.41　mg/ml crude herb, respectively. It was also displayed to inhibit biosynthesis of 12-HHT in the platelets. CONCLUSION　Biota orientalis leaves contain anti-inflammatory components and the anti-inflammatory mechanism was related with inhibiting metabolism of arachidonic acid.

AIM To investigate the anti-inflammatory eff ec t of total flavonoids isolated from Platychadus orientalis and its mechanism . METHODS The inflammatory models in mice and swelling of rats hind paws were induced by dimethylbenzene and carrageenan respectivel y. The biosynthesis of leukotriene and ?-glucuronidase release in the cells we re measured by HPLC and fluorescence spectrophotometer respectively. RES ULTS Total flavonoids isolated from Platychadus orientalis remarkably inhibited the ear edema induced by dimethylbenzene in mice at the dose of 12.5 ～50.0 mg?kg -1 and the swelling of rats hind paws induced by carrageenan at the dose of 25.0～50.0 mg?kg -1 . Total flavonoids at final concentrati on of 5.0～125.0 mg?L -1 inhibited 5-HETE and LTB 4 synthesis by 30.5%～ 87.3% and 27.8%～84.3% respectively. In comparision with controls, Total flavono ids at final concentration of 5.0～45.0 mg?L -1 inhibited ?-glucuronidas e release by 13.4%～32.2%. CONCLUSION Total flavonoids isolated f rom Platychadus orientalis has an anti-inflammatory effect which may be rel ated to inhibiting 5-HETE and LTB 4 production and ?-glucuronidase release.

AIM: To explore the effect of luteolin on the metastasis of ovarian carcinoma HO-8910PM cells in vitro, and to elucidate its mechanisms. METHODS: The in vitro invasion and mobility of HO-8910PM were measured by Boyden chamber assay after exposure to luteolin for 6 h. Gelatinase activity was tested by gelatin zymography assay. The expression of tissue inhibitor of metalloproteinase-1 (TIMP-1), nm23 mRNA and that of ERK2 protein were tested by RT-PCR and Western blotting, respectively. RESULTS: Luteolin significantly inhibited in vitro invasiveness and mobility in HO-8910PM cells in a dose dependent manner as measured by Boyden chamber assay. Luteolin inhibited the MMP-9 secretion from HO-8910PM cells. Luteolin did not affect the mRNA expression of TIMP-1 and nm23. Luteolin also decreased ERK2 expression. CONCLUSION: Luteolin dose-dependently inhibited the metastasis of HO-8910PM cells in vitro. Inhibition of MMP-9 secretion and ERK2 expression may be involved in the anti-metastasic process of luteolin.

Objective To investigate the main risk factors influencing the pre-hospital delay of patients with acute ischemic stroke (AIS) for preventing methods.Methods A retrieval was done across the epidemiologic studies on pre-hospital delay of AIS patients during 2004 to 2015 using the key words of ischemic stroke,prehospital delay,treatment delay.According to the inclusion and exclusion criteria,the literature was collected and the literature quality was assessed.The data were extracted for meta-analysis by RevMan software.Results Sixteen epidemiologic studies were included.Totally,there were 2,966 cases of prehospital delay and 2,468 cases of non-delay.The pooled OR values and 95％ CI by multivariate analysis were as follows:the degree of awareness of stroke was 0.5 (0.3,0.82),emergency medical service (EMS) was 0.49 (0.29,0.85),National Institute of Health Stroke scale (NHISS) score 0.58 (0.36,0.95),outpatient visit as first visit 4.28 (1.44,12.74),distance 0.76 (0.61,0.95),medical history of ischemic stroke 0.37 (0.18,0.79) (with significant differences in OR value,P＜0.05).Conclusions The protective factors for pre-hospital delay of acute ischemic stroke patients include:strengthened awareness of stroke,effective EMS,high NHISS score,short distance,medical history of ischemic stroke.The main risk factor is that their outpatient visit is their first visit for medical treatment.Therefore,we need to enhance the health education to the patients and their families about awareness of stroke,improve the use of EMS and build complete and efficient green path for the stroke patient.

The incidence of venous thromboembolism after spinal cord injury is high, and its diagnosis and prevention received much attention in clinical research in recent years. Because of the special characteristics, the prevention of venous thrombosis should be combined with basic prevention, physical prevention and drug prevention. According to the different situations of venous thromboembolism in patients with spinal cord injury, the prevention methods need to adjust to carry out multidisciplinary comprehensive treatment.
